To all whom it may" concern Be it lmown that l, FRAN Wmonnnt, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, Improvements in Hydrocarbon-Heaters for Carburetors, of which the following is a specification.

My invention. relates to improvements in hydrocarbon heaters for carburetors, and the object or my improvement is to provide for a carbureter an attachment or auxiliary heating means for heating kerosene or any other relatively slowly vaporizing hydrocarbon previous to its deposition in the can bureter to insure its constant vaporization therein.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which the figure is a diagrammatic elevation, in. partial longit-ndinal section, of my improved hydrocarbon heater as operatvely connected to a carbureter.

The carbureter 11 may vbe of any type, the one shown being a float-valve controlled one as ordinarily employed in association wit-h an internal-combustion motor, and having a delivery-pipe 12 in communication with the manifold 13 of such a motor not shown.

The numeral 1% denotes a valve-chamber whose valve is controlled by a hand-wheel 16, and'receives a supply of light easily vaporized hydrocarbon, such as gasolene, by

way of a pipe 17 leading to a reservoir, not shown, the valve chamber having a deliverynipple mounted within the manifold 13, and provided with aplurality of small orifices to spray the gasolene in small streams to insure its instantaneous vaporization.

My improved heating attachment is adapted for connection to the carbureter to deliver lrerosene or other relatively heavy hydrocarbon. there'into in a suitably heated state, from a reservpir 1,

A. tube 2, which may be of owpled sec, tions as shown, leads from the reservoir 1 into the carburetor 11.

The numerals 4c and 3) denote sections of a pipe placed in communication by means of a "t -coupling 3, and serving as a conduit for the exhaust gases of the motor. The section of said pipe has a rock-valve 6 mounted therein, operated. manually by means of a have invented certain new and useful canlc-handle 7, or by any other desired means, to variably restrict the passage of gases thcrethrough.

The numeral 8 denotes a section of pipe inclosing a part of the tube 2, said tube 2 being passed through the"l"-couplinp 3 and centrally through the pipe 8. One end of the pipe ,8 is threaded into said 'l'-coupling 3, the other end being threaded into an elbow-coupling 9, the latter delivering into ,a branch exhaust-pipe 10, and the tube 2 der varying degrees of temperature of the atmosphere. The gases passing through the pipe 8 heat the hydrocarbon flowing through the tube 2 previous to' its delivery into the carbureter, where the hydrocarbon is received at a temperature insuring its immediate vaporization, which condition is constantly maintained as long as the motor is in operation, or while heated gases are deflected into the pipe 8 by the baflling action of the valve 6.

My improved heating attachment is simple and easily assembled, as also quickly dis assembled for the purpose of cleaning or carriage, and may be connected to any kind of carbureter Having described my invention, What I claim as new, and desire to secure by Letters Patent, is:

In combination, a tank, a conduit in communication with said tank, a pipe for carrying a heated fluid under head and traversed transversely by said conduit, a throttle-valve in said pipe located beyond the place of traversing of said conduit, and a by-pass in. communication with said pipe at the location of its traversing by said conduit, the conduit fill being carried through a. part of said by:

pass interiorly in spaced relation thereto.
